Pupil achievement and behaviour in schools was earlier seen as given by socioeconomic and biological factors. But since the late 1970s the school effectiveness research has come to give school factors a much greater role for pupils’ attainments. Research has shown that schools´ pedagogical and social climate, which is to be seen as a complex product of deeply felt values and norms held by school principals and teachers and developed through practical actions, can explain variations in effectiveness between schools. Effectiveness is here to be seen as a higher mean cognitive and non cognitive student outcome than is expected with regard to initial attainment or family background. In this context all schools can be effective.

The purpose of this dissertation is to study the pedagogical and the social climate in two secondary schools in order to answer the question of how the climate can describe their conditions for future evolvement in effectiveness. The method of data collection is qualitative enquiries and has been conducted through interviews with principals, teachers and pupils. Our two schools are based in the same council and have a similar intake of pupils. The results derived from the study show that one school has a better pedagogical and social climate than the other which at the same time gives it greater conditions for future effectiveness.
